Description

Technical Field

[0001] This utility model relates to the field of grinding wheel production equipment technology, specifically a grinding wheel production positioning mechanism. Background Technology

[0002] Grinding wheels, also known as bonded abrasives, are abrasive tools in which ordinary abrasive grains are bonded together with a bonding agent to form a specific shape and possess a certain strength. They generally consist of abrasive grains, a bonding agent, and pores; these three parts are often referred to as the three essential elements of bonded abrasives. Based on the type of bonding agent used, common types include ceramic grinding wheels, resin grinding wheels, and rubber grinding wheels. During the production process of grinding wheels, factories need to use clamps to hold the grinding wheels in place.

A positioning mechanism is located on one side of the testing table. The positioning mechanism includes a movable seat, with a rotating seat rotatably connected to its upper end via a bearing. A fixing component is located on the upper end of the rotating seat. The fixing component includes a drive chamber inside the rotating seat, containing a first motor. A rotating disk is driven by the first motor, and the rotating disk has threads. Moving blocks are symmetrically threaded onto these threads. Guide rods are slidably connected to the moving blocks, with both ends of the guide rods fixedly connected to the rotating seat. The upper end of the rotating seat is recessed inward to form a movable groove that mates with the moving blocks, guide rods, and rotating disk. Each moving block has a fixing block at its upper end. The rotating seat has a rotating component, including a toothed belt on its outer side, which facilitates the fixing and positioning of grinding wheels of different sizes. The slope design makes the grinding wheel more stable, ensuring the effectiveness of the positioning mechanism. However, it can only fix the grinding wheel in one direction, resulting in low stability of the grinding wheel fixation. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4In this embodiment of the present invention, a grinding wheel production positioning mechanism includes a processing table 1. A column 11 is rotatably mounted on the upper side of the processing table 1 via bearings, and a positioning platform 10 is mounted on the upper end of the column 11. A first motor 13 is driven to the lower end of the column 11 via a gear set 12, and the first motor 13 is fixedly mounted on the processing table 1. This allows the first motor 13 and the gear set 12 to drive the column 11 and the positioning platform 10 to rotate horizontally for adjustment, thereby facilitating the adjustment of the fixed grinding wheel water-processing position. The upper side of the positioning platform 10 has a first slider 4 and a second slider 5 with opposing threads on the upper side via a lead screw. The lead screw includes a lead rod 3 rotatably mounted in a groove 2 on the upper side of the positioning platform 10, and two oppositely arranged outer ends of the lead rod 3. The first slider 4 and the second slider 5 are respectively connected to two opposite external threads. One end of the lead screw 3 is connected to a second motor. The upper side of the first slider 4 and the second slider 5 are provided with positioning clamps 6, so that the first slider 4 and the second slider 5 are moved in opposite directions by the lead screw to adjust. The two opposing positioning clamps 6 are used to clamp and fix the grinding wheel from the inside to the outside. The top of the storage groove 7 in the middle of one side of the positioning clamp 6 is hinged to the first cylinder 14. The lower end of the first cylinder 14 is provided with a top positioning plate 15. The top positioning plate 15 is driven by the first cylinder 14 to move down and press on the top of the grinding wheel. The positioning is achieved by acting in two directions in sequence, which makes the grinding wheel more stable and convenient to operate.

[0024] like Figure 3 and Figure 4 As shown, in order to adjust the retraction of the first cylinder 14 and the top positioning plate 15, a lateral telescopic mechanism is also provided between the first cylinder 14 and the storage compartment 7. The lateral telescopic mechanism includes a second cylinder 16 fixedly installed on the inner wall of the storage compartment 7. One end of the second cylinder 16 is provided with a limiting roller 19 through the support frame 18. The lateral telescopic mechanism also includes a limiting seat 17 provided on one side of the first cylinder 14, and the limiting roller 19 is slidably installed with the limiting sliding hole 20 in the limiting seat 17. This allows the limiting roller 19 to slide and adjust the limiting seat 17 on one side of the first cylinder 14 by driving the second cylinder 16, thereby enabling the tilt adjustment of one end of the first cylinder 14. When the first cylinder 14 is not in use, it can be retracted into the storage compartment 7, improving the flexibility of the top positioning plate 15 and facilitating the removal and placement of the grinding wheel.

[0025] like Figure 1 As shown, in order to improve the stability of the positioning clamp 6, a guide rail 9 is provided on the inner wall of the groove 2, and guide grooves 22 are provided on both sides of the first slider 4 and the second slider 5, which are slidably arranged with the guide rail 9. These grooves are used to guide the first slider 4 and the second slider 5 during movement adjustment, which helps to improve the stability of the positioning clamp 6.

[0026] like Figure 1 and Figure 4As shown, in order to improve the stability of the grinding wheel clamping and fixing, the clamping end face of the positioning clamping block 6 is set as an arc end face, and the outer end face of the positioning clamping block 6 is provided with a first protective pad 8. The positioning platform 10 is a circular platform, the top positioning plate 15 is a rectangular slider, and a second protective pad 21 is provided on one side of both the positioning platform 10 and the top positioning plate 15. The first protective pad 8 and the second protective pad 21 are both rubber pads, which increases the anti-slip properties of the positioning clamping block 6, the positioning platform 10 and the top positioning plate 15, which is beneficial to improving the stability of the grinding wheel clamping and fixing.

[0027] The working principle and usage process of this utility model are as follows: When in use, the grinding wheel to be positioned is placed flat on the middle of the positioning table 10, and the two positioning clamps 6 are set through the central mounting hole of the grinding wheel. Then, the first slider 4 and the second slider 5 are moved in opposite directions by the lead screw to adjust them. Thus, the two positioning clamps 6 moving in opposite directions are used to clamp and fix the grinding wheel laterally from the inside to the outside. Then, the top positioning plate 15 is driven to move down and press on the top of the grinding wheel by the first cylinder 14. The positioning is achieved by acting in two directions in sequence, which makes the stability of the grinding wheel fixed high and the operation convenient and quick.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
